Engineered for extended drain intervals up to 500,000 miles as set by equipment manufacturers for over-the-road trucks and heavy equipment. Provides long life in passenger cars and trucks. Excellent all season summer and winter performance. Outperforms all conventional gear oils.

AMSOIL Long Life Synthetic Gear Lube is an extended-drain gear lube
engineered to last several times longer and protect gears better than
conventional gear oils. This exclusive AMSOIL formulation of premium
synthetic base oils and high-performance additives resists acid, carbon
and varnish formation from oxidative breakdown. Components
run cleaner and last longer. AMSOIL Long Life Synthetic Gear Lube
is shear-stable and reduces friction. It maintains its viscosity during
extended service for maximum wear control and is fuel-efficient. The
superior cold-temperature fluidity and high-temperature stability properties
of AMSOIL Long Life Synthetic Gear Lube make it excellent for
all-season use. AMSOIL Long Life Synthetic Gear Lube helps extend
equipment life and reduce maintenance costs.

Use AMSOIL Long Life Synthetic Gear Lube in differentials, manual transmissions or
other gear applications where one or more of the following standards are specified:
API GL-5 & MT-1, MIL-PRF-2105E, Dana* SHAES* 234 (Formerly Eaton* PS-037) for
250,000 miles, Dana SHAES 256 (Formerly Eaton PS-163) for 500,000 miles, Dana
SHAES 429A, Mack* GO-J & GO-J+, Meritor* 0-76N (75W-90) & 0-80 (80W-140) plus
hypoid gear oil specifications from ZF TE-ML 07A and 08 foreign and domestic manufacturers
such as GM*, Ford* and Daimler* Chrysler*. It can also be used in rear axles
where API Service GL-4 lubricant is recommended.

High Load gear and bearing protection

Protection from rust and corrosion

Better cold-weather shifting

Severe Service

Cars, SUVs, Light Trucks

Drain at 100,000 miles
of service or according to the owners
manual, whichever is longer

Heavy Duty Class 8 Line
Haul

Follow the
OEM drain interval (miles or hours) for
synthetic oil up to 500,000 miles or three years,
whichever comes first.

Vocational/Delivery

Follow the
OEM drain interval (miles or hours) for
synthetic oil up to 120,000 miles or three years,
whichever comes first.

Heavy Duty Off-Road

Follow the
OEM drain interval (miles or hours) for
synthetic oil up to 100,000 miles or two years,
whichever comes first.

For product service life in non-differential applications, consult
owner’s manual or the OEM for either normal or severe synthetic
oil service intervals. Where service intervals are unavailable,
drain at twice the interval for conventional oil.

Note: AMSOIL does not support extended drain intervals where
water contamination occurs. Check and service the gear oil
frequently when water contamination is possible.

Gear oils should be changed more frequently when operating
vehicles or equipment in dusty or dirty conditions unless the
gear system is properly sealed and equipped with membrane-type breathers.

COMPATIBILITY
AMSOIL Long Life Synthetic Gear Lube is compatible with
conventional gear oil. Mixing AMSOIL gear oils with other oil,
however, reduces the oil’s benefits and nullifies the extended
service life recommendations.

I believe fully that Amsoil synthetics are the class of the field in all applications , I use their engine and mix oils in my quads and jet ski , so I seen their extended life gear oil I had to get it for my pickup , it might sound like an ad , but , Amsoil is all good stuff

It's difficult to give a review of a long term oil such as differential lube. But, Amsoil in my 4.2 and my 4.0 Jeep engines was immediately noticed. Jeep in-line 6 motors tend to have valve noise on start up. Totally gone now ! Love that Amsoil ( 10w30). Now switched all 3 Jeeps to Amsoil

Put this in my 2wd Tacoma open differential, 10,000 miles so far and no issues. I purchased the premium AMSOIL synthetic product for its superior quality and long service life... will last longer and protect my vehicle better than conventional, so in the long run it's definitely worth the added cost.
